Jessie Grimes, an Irish clarinettist, poses for a photograph in west London, Britain June 7, 2016. Grimes is concerned that a post-EU Britain may have to re-instate border controls between the Republic of Ireland and Northern Ireland, which is part of the United Kingdom. "I can't see that going peacefully," she said, recalling the political violence that blighted Northern Ireland when she was a child. Picture taken June 7, 2016.
